Pandi,
My apology. it seems that the CLI forces the minimum to be = max (1500,
rate/2000).
The CLI and the documentation are both misleading as I tried all
combinations below:
TermServ(config-if)#$input 2500000 1000 2000 conform-action tra exce drop
Illegal normal burst size
Increasing normal burst size to 1500
TermServ(config-if)#rate-limit input 8000 1000 2000 con tr ex dr
Illegal normal burst size
Increasing normal burst size to 1500
TermServ(config-if)#rate-l in 20000000 1000 2000 con tr ex dr
Illegal normal burst size
Increasing normal burst size to 10000
Illegal extended burst size
Increasing extended burst size to 10000
TermServ(config-if)#$input 2500000 1000 2000 conform-action tra exce drop
Illegal normal burst size
Increasing normal burst size to 1500
TermServ(config-if)#do sh ver | i IOS
Cisco IOS Software, 3600 Software (C3640-JK9O3S-M), Version 12.4(16),
RELEASE SOFTWARE (fc1)
HTH,
Joseph.
